I've worked in C#.NET and Perl for about ten years in the business sector (healthcare, financial, management software.) I recently switched to the mobile games industry working for a company where I do Android porting of their iOS titles and I still maintain and support .NET software (keeps me from getting too rusty.)
I also have my own company, Offbit Studios, where I put out little mobile games for iOS and Android. Just a side thing but fun.
